Application filed October 10, 1922. Serial No. 593,5;19.

, Shades, of whichthe following is a speciiicati'on.

In carryingout the present invention it is my purpose to provide a window shade which will be; constructed in such manner that the same may be raised and lowered without employing the ,us-ualspring roller and which, whenin lowered position, will cover the entire window, while when in raised position the lower'half of the window will be opened and the top half only covered. V

It is also my purpose to providea win dow shade which will embrace the desired features of simplicity, eiiiciency and durability, which may be manufactured and marketed at small cost and which will embody comparatively few parts, and these so arranged and corelated as to reduce the pos sibility of derangement to a minimum.

\Vith the above recited objects in view, and others of a similar nature, the invention resides in the construction, combination and arrangement of parts set forth in and-falL ing within the scope of the appended claims;

In the accompanying drawings:

Figure 1 is a front elevation of a window shade constructed inaccordance with my invention and applied to a window, the shade being shown in open position.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3 is a similar view to Figure 1, showing the shade in closed position.

Figure 4 is a vertical sectional View on'the line 4-4 of Figure 3.

Figure 5 is an enlarged view showingone of the bearings for the rollers.

Figure 6 is a sectional view on the line 66 of Figure 5.

Referring now to the drawings in detail, 1 and 2 designate rollers arranged respectively at the top and center of a window frame, clearly shown in Figures 1 and 3 of the drawings- Each roller 12 is journaled at its ends in bearings 3. In the. present instance, each bearing 3 comprises a base 4 formed with openings 5 through whichscrews or other fastening devices may be passed in order to fasten the bearing to v the window frame. Outstanding from the base 4 1s a circular head 6 having its inner side formed with an opening 7- and with a counter-sunk recess 8 at the center of the inner wall of the opening 7. The opening tially reduced, as at. 11, and fits into the counter-sunk recess 8, as clearly shown in Figure 6 of the drawing. The marginal 7 at the juncture of the circularside wall edge; ofthe enlargement-1O contiguous to the race-.way9 is formed to provide a raceway 12 and within these raoe-ways are mounted anti-friction balls 1-3 that enable the roller to revolve freely within the bear ing members. These bearing members support the rollers 1 and 2 in proper positions atthe top and center of the windowframe. Trained over the rollers 1 and 2 is an endless shade section 14 having an inner run that lies nextto the window frame and an outer run that is arranged beyond the inner run, clearly. shown in Figures 2 and 4 of the drawings. Stitched or otherwise secured to, the inner run of the endlessshade section 14 at one end thereof is a shade section 15. The lower end of the shade section 15 is stiifened by the usual strip 16 that is equipped with a finger pull 17 The end of the outer run of the shade section 14 remote from the end of the innerrun to which the shade section 15 is secured is provided with an eyelet 18 from which depends a cord i 1.9 equipped at its lower end with a finger. ring 20. i

In practice, when-it is desired to close the shadethe finger pull 17 is pulled down, thereby lowering the sections 15,, and in the downward movement of the sections 15 the endless shade section 14 rotates about the rollers 12 so that the section 15 may be pulled down, as shown in Figures 3 and 4 of the drawings. When it is desired to raise the section 15 a pull is exerted upon the ring 20, thereby reversing the direction of rotation of the section 14, so as to raise the' shade section 15 to the position shown in Figures 1 and 2 of the drawings.

I have entered into a detailed lescripticm of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention with a view to in'ipartingz afull, clear and exact understanding of the said embodiment. I do not desire, however, to'be understood as confining myself to the said specific construction and relative arrangement of parts, inasmuch as i the future practice of my invention such changes or modifications may be made as fairly fall within the scope of my invention as defined by my appended claims.

' iavingthus described the invention, what is claimed as new, is r 1. In a window shade, rollers mounted at the top and center, respectively. of the window frame, an endless shade section on said rollers, a second shade section secured to the inner run of the first mentioned section at one'end thereof and a pull ring: secured to the outer run of said endless shade section at the relatively opposite end thereof.

2. I a window shade, rollers mounted at the top and center. respectively. of the window frame, an endless shade section on said rollers, a second shade section secured to the inner run of the first mentioned section at one end thereof, a pull ring secured to the outer run of said endless shade section at the relatively opposite end thereof, and antifriction bearing members supporting the ends of each of said rollers.

3. In a window shade, rollers mounted at the top and center, respectively, of the Window frame, an endless shade section on said rollers, a second shade section secured to the inner run of the first mentioned section at one end thereof, a pull ring secured to the outer run of said endless shade section at the relatively opposite end thereof, antifriction bearing members supporting the ends of each of said rollers, each bearing member comprising a circular head formed with an opening on its inner side and with a counter-sunk depression at the center of the inner wall of said opening and a disklike enlargement adjacent to the end of said roller engaging in said opening, the end of said roller being circumferentially reduced and fitting into said depression and antifriction bearing members between said disklike enlargement and the wall of said opening.

In testimony whereof I aflix my signature.
